Also, besides the low z-jerk, your extruder jerk is also very low which can cause issues especially on arcs, circles, etc. I would raise your extruder jerk to at least over 1000.
I tried the 0.9 degree LDO motors but ended up going back to the 1.8degree ones. The 1.8 degree for me are much quieter and I saw no improvement with the 0.9 degree ones so I switched back.
I have a v-core 3.1 500mm using a Duet 6HC, my motor settings are as follows
M569 P0.0 S0 ; physical drive 0.0 goes backwards M569 P0.1 S0 ; physical drive 0.1 goes backwards M569 P0.2 S0 ; physical drive 0.2 goes backwards M569 P0.3 S0 M569 P0.4 S0 M569 P121.0 S1 ; physical drive 121.0 goes backwards - lgx forward / BMG backward M584 X0.0 Y0.1 Z0.2:0.3:0.4 E121.0 ; set drive mapping M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation M350 E32 I0 ; try extruder no interpolation M92 X80.37 Y79.85 Z808.8 E1134 ; TEST CALIBRATION XY STEPS M566 X800 Y800 Z35 E2000 P1 ; instantaneous /jerk settings) M203 X21000.00 Y21000.00 Z1000.00 E3600.00 ; set maximum speeds (mm/min) M201 X3000.00 Y3000.00 Z200.00 E3600 ; set accelerations (mm/s^2) M906 X1900 Y1900 Z1700 E600 I30 ; set motor currents (mA) and motor idle factor in per cent - 600 for lgx motor / 900 for BMG M84 S30
